Movable Four-Window Sight Glass
Movable Four-Window Sight Glass
Core Differentiation:Made of copper base + chrome plating with a movable structure, distinct from "fixed/aluminum alloy" sight glasses. It combines copper's high-pressure resistance (≤0.5 MPa) & excellent thermal conductivity (avoiding medium temperature interference) with chrome plating's strong corrosion resistance & long-lasting mirror finish. Available in 3/4" and 1" sizes, suitable for accurate medium observation in scenarios requiring angle adjustment, high pressure, or corrosion resistance.
1. Materials & Core Advantages
- Copper + Chrome Plating Composite Structure: Copper base resists high pressure and ensures stable thermal conductivity; chrome plating enhances oil-gas corrosion/scratch resistance, maintaining mirror texture long-term with durable, clear windows.
- Movable Design: Four high-borosilicate glass windows support angle fine-tuning for 360° dead-angle-free medium observation, suitable for complex pipeline layouts needing flexible viewing angles (balancing structural stability and observation flexibility).
2. Key Specifications
- Sizes: 3/4", 1" (compatible with NPT/BSPT/G threads).
- Working Pressure: ≤0.5 MPa.
- Temperature Range: -15℃ ~ +80℃.
3. Applications & Usage
- Superior Scenarios (vs. fixed/aluminum models)**：
① High-pressure hydraulic systems (≤0.5 MPa): Require angle adjustment to observe hydraulic oil and check pump/valve/pipeline blockage/leakage;
② Chemical/complex pipelines: Chrome plating resists chemical corrosion, and the movable structure adapts to flow monitoring of oils/weakly corrosive media in complex layouts;
③ High-end equipment matching (machine tools, precision hydraulic stations): Chrome-plated mirror finish for aesthetics, and movable design meets flexible observation needs
- Usage Steps:
1. Select Size: Choose 3/4" or 1" matching pipeline interface & thread;
2. Sealed Installation: Wrap threaded end with oil-resistant tape, screw clockwise into pipeline (fine-tune movable parts’ angle before reinforcement to avoid copper thread slipping);
3. Observation & Judgment: During operation, observe medium via angle-adjustable four windows — uniform flow & no impurities → normal system; disordered flow/foreign matter → inspect pipeline/filter.
